LayoutInflater.Factory的夜间模式

自定义实现个Factory，可以用来解析自定义的属性。
public interface Factory {
        /**
         * Hook you can supply that is called when inflating from a LayoutInflater.
         * You can use this to customize the tag names available in your XML
         * layout files.
         * 
         * <p>
         * Note that it is good practice to prefix these custom names with your
         * package (i.e., com.coolcompany.apps) to avoid conflicts with system
         * names.
         * 
         * @param name Tag name to be inflated.
         * @param context The context the view is being created in.
         * @param attrs Inflation attributes as specified in XML file.
         * 
         * @return View Newly created view. Return null for the default
         *         behavior.如果返回一个view， 那么就会直接加入到原有View树中去。 如果返回null，则会走原来类似于onCreate的方法。
         */
        public View onCreateView(String name, Context context, AttributeSet attrs);
    }

 LayoutInflater.Factory这个值设置到LayoutInflater中，而LayoutInflater的获得又是跟谁Context而来的。也就是说相同的Context有着相同的LayoutInflater，那就可以重用相同的LayoutInflater.factory

 在BaseActivity中加入自己的Factory

　　　　 mLayoutMode = new BDLayoutMode(); // 针对该Activity的一些存储
        mLayoutInflateFactory = new BDLayoutInflateFactory(); //自定义的LayoutInflateFactory
        mLayoutInflateFactory.setViewMode(mLayoutMode);
        getLayoutInflater().setFactory(mLayoutInflateFactory); //  给该Activitry设置factory

这样在BDLayoutInflateFactory中就可以自定义解析自己关心的值了。

在BaseActivity的OnResume中开始，遍历每一个控件。
